Variable in While Loop Nested If
Hi all,

I'm having problems with the setting a variable in a nested if statement. It doesn't seem to change even if it mets the 'if' condition.
My script essentially looks for a user name from the output from a kerberos command.
When I find the user name, I tried to change a variable and exit the script.

I'm using sh under Fedora Core 5.

Here is part of my script:

#!/bin/sh

#Constants and Globals
USER_EXISTS=1
USER_DOESNT_EXIST=0
user_name=
g_exitcode=

#note: I parse the $user_name from the command line arguments

#Main
g_exitcode=$USER_DOESNT_EXIST

kas list | while read i
do
echo "$i : $user_name"
#compare the user_name with each entry in the kas database
if [ "$user_name" = "$i" ]; then
#Match found
g_exitcode $USER_EXISTS
break
fi
done

exit $g_exitcode

So, even if a match is found, and it enters the nested if statement and sets the g_exitcode to USER_EXISTS at that point, I always exit the script with g_exitcode=USER_DOESNT_EXIST.

Sorry, I'm a little new to scripting. Any help would be appreciated

NAME

       asadmin-delete-file-user, delete-file-user - removes the named file user

SYNOPSIS

       delete-file-user  --user  admin_user  [--password  admin_password] [--host localhost] [--port 4848] [--secure|-s] [--passwordfile filename]
       [--terse=false] [--echo=false] [--interactive=true] [--authrealmname auth_realm_name] user_name

       Deletes the entry in the keyfile with the specified username. If the auth_realm_name is not specified, an entry is created in  the  default
       keyfile. If auth_realm_name is specified, an entry is created in the keyfile where the auth-realm name in the domain.xml file points to.

       This command is supported in remote mode only.

OPTIONS

       --user		       authorized domain application server administrative username.

       --password	       password to administer the domain application server.

       --host		       machine name where the domain application server is running.

       --port		       port number of the domain application server listening for administration requests.

       --secure 	       if true, uses SSL/TLS to communicate with the domain application server.

       --passwordfile	       file containing the domain application server password.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on the standard output. Default is false.

       --interactive	       if set to true (default), only the required password options are prompted.

       --authrealmname	       name, in the domain.xml file, where you have different stores for file auth realm.

OPERANDS

       user_name	       name of file user to be deleted.

EXAMPLES

       Example 1: Using the delete-file-user command

       It is assumed that an authority realm has already been created using the create-auth-realm command.

       asadmin> delete-file-user --user admin1 --password adminadmin1
       --host pigeon --port 5001 --authrealmname auth-realm1 sample_user
       Command delete-file-user executed successfully

       Where: the sample_user is the file user deleted.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
